Bear with me:
I have a data set that is begging for the tf-idf transformation to account for a long tailed distribution of degree. Right now, it is in the form of a network where a tie represents co-purchases, but because some products are wildly more popular than others, they end up as the strongest ties for literally everything.
The problem is that the technology I'm using still doesn't have a built in log function. What are the alternatives to idf to adjust for uneven distribution of ties?
I'm also open to any other solutions in network analysis for adjusting strength of tie based on centrality.
